XC28 FORK - USER GUIDE
AIR BIKE XC28 FORK USER GUIDE 3
1. Air-Bike forks have been specially designed
for a single rider on mountain bike trails
and similar off-road conditions. They are not
designed for race or downhill riding
2. Please ensure you Air-Bike Fork is fitted and
installed professionally. We recommended
that you have a qualified bicycle technician/
mechanic install the fork. If it is not installed
correctly then it will become dangerous and
could result in severe injuries or death.
3. Following on from your Forks, please ensure
the brakes are installed and correctly
adjusted before riding. Again, incorrect
installation or adjustment could result in
severe injuries or death.
4. Ensure you inspect your Fork regularly, do
not ride or stop riding your bike immediately
if you notice any damage such as broken/
dented parts or components. Or if you see
any oil leaking from the fork. Check for
excessive top out or bottom out and along
with visual damage if you hear any unusual
noises please stop and inspect your fork and
then head to a qualified mechanic to ensure
everything is ride worthy.
5. We advise you do not try to modify your fork
in any way. Any modification to your Air-Bike
Fork will void the warranty and could cause
severe injuries or death.
6. If you need to replace any parts the only use
authorized Air-Bike Fork replacement parts.
Use of any unauthorized aftermarket parts
will void the warranty and could cause failure
of the shock.
7. If you are using a bicycle carrier/rack that
fastens the bicycle at the front dropouts
only, then the rear wheel must be securely
fastened to prevent movement of the
rear wheel. Movement of the rear wheel
will damage the front dropouts, and this
damage may not be visible to you.
8. Air-Bike Forks do not come with any
reflectors to use on roads. Therefore, if you
are planning on ridding your bike on the
road or on bicycles paths please install the
required reflectors. You can contact your
main dealer for this.
9. Please ensure you always check your wheels
before riding, look at the quick release
skewers and/or thru axles. These need to be
adjusted and tightened correctly.
10. When purchasing a tyre for your Air-Bike
Fork, it is important to follow the tyre
clearance guidelines. If you do not do this
correctly then this can create unnecessary
contact/friction and bicycle malfunction
resulted in serious injury or death.
11. It is important to know your limits when
riding dependant on your skills and
experience. Please be sensible, have fun but
know your own limitations.
IMPORTANT SAFETY
INFORMATION
4 AIR BIKE XC28 FORK USER GUIDE
1. Firstly, check the function of your fork.
Here you are looking at the torques of the
mounting’s screws and nuts on bottom of
lowers (torque suggested: bolt: 10Nm, nut:
8Nm)
2. Look for dents, cracks, discoloration, signs
of wear, signs of corrosion (not matter how
minimal, this can be maintained with oil
applied via a cloth) but also check for oil
leaks.
3. The disassembly and cleaning of the entire
fork (inside and out). This includes cleaning
and lubricating seals and slider sleeves.
Please check the torques and adjust them to
your preference.
4. Please make sure that before disassembly
you check the slider sleeve play of the fork.
You can do this by applying the front wheel
brake, smoothly push the bicycle back and
forth at the handlebar stem shaft and then
you can replace the slider sleeves if the play
is excessive (this shouldn’t be any than 1 mm
at the fork brace).
MAINTENANCE PLAN
• Your need to periodically maintain, inspect and
clean you fork. If you are riding in extreme weather
(winter, wet. muddy conditions or over rough
terrain then it is advised you should be maintaining
your fork more frequently.
• After every ride make sure you clean the fork
stanchions (tubes) dust seals and maintain with
an oily cloth. When you are doing this check the
stanchions for dents, scratches or corrosion or
leaking oil.
• Torque values of bolts and fasteners must be also
be checked. To maintain optimum performance, it
is recommended that your fork be disassembled,
inspected, cleaned, dried and re-lubricated. After
you’ve been on a ride simply wipe down the
stanchions and the seal.
• Clean and inspect your bushings, check fastener
torques every 100 hrs (if the seasons are changing
and rain/snow/cold is expected get this done to
protect all parts from the harsh environment)
MAINTENANCE
The reality is the more you look after your Air-Bike
Fork the longer it will last at optimum performance.

Your Air Bike fork has been adjusted to provide
the optimum preload for the spring and is NOT
adjustable.
PRELOAD & SAG
The “lock-out” function closes the compression
damping of the fork when riding standing up or
riding uphill. The fork is not locked 100%. A couple of
millimetres of the suspension travel remains moving,
called “anti-blow-off system “. This system protects
you when riding in demanding terrain in case you
forgot to unlock the fork.
Regardless, you should never switch your fork to “lock-
out mode” when riding in demanding terrain or when
jumping. The fork may become damaged when it is
compressed under a high load. This can also lead to
accidents and injuries.
